chore(D.5.1): remove temp geometry probe + add RestrictionDB-skip parse test

Task 1: remove the [D.5.1 PROBE] bottom-right rect-dump block from the
toolbar mount in GameWindow.cs. The block iterated 7 element ids and
logged ScreenPosition/Width/Height/Type; it was marked temporary and is
now superseded by the chrome window-frame fix. The kept [D.5.1] startup
diagnostic Console.WriteLines (digit arrays, toolbar ready, window from
LayoutDesc) are untouched.

Task 2: add TryParse_HouseRestrictionsSkipped_ThenIconOverlayCaptured to
CreateObjectTests.cs. Exercises the variable-length RestrictionDB skip
(weenieFlags bit 0x04000000: 12-byte fixed header + 4-byte hash-table
header + count*8 entries) followed immediately by IconOverlay (0x40000000)
and IconUnderlay (weenieFlags2 0x01 via IncludesSecondHeader 0x04000000).
Proves the skip lands the cursor at the right position for both capture
fields. 301/301 tests pass.
